IPC: H03H9/64
Filed: 1990-03-28
Abstract: PURPOSE:To obtain a surface acoustic wave multiplex mode filter whose adjustment of pass band width is easy by connecting a varactor element to a conductor pattern connecting to an interdigital electrode of a surface acoustic wave resonator. CONSTITUTION:Surface acoustic wave resonator comprising interdigital electrodes 11-14 and reflectors 15-18 having the electrodes inbetween is arranged closely onto a piezoelectric substrate 10. The electrodes 12, 13 are connected by a conductor pattern 19 formed on the surface of the substrate 10, the conductor pattern 19 is connected to a varactor diode 21 and to ground via a conductor pattern 20, and a varactor diode 21 connects to a voltage application means.

Inventor: ENDO KAZUHIRO
IPC: F25B1/00
Filed: 1993-04-06
Abstract: PURPOSE:To provide an air conditioner wherein, when the compressor is not working and its temperature has fallen low, a change in the composition of a nonazeotropic refrigerant due to a difference in the solubility in the oil of the different components of the nonazeotropic refrigerant, is reduced to a small degree so that the problem relating to combustibility to be caused by a change in composition of the mixture is solved. CONSTITUTION:An air conditioner referred to above employs a nonazeotropic refrigerant, which contains a combustible component, in the refrigeration cycle comprising a compressor 1, outdoor heat exchanger 13, expansion valve 16, and indoor heat exchanger 18. This air conditioner is equipped with a means of heating the compressor when the compressor is not working; that is, the compressor 1 is provided on its outer side with an electric heater 9 for heating it.

Title: Brake shoe holding mechanism for drum brake
Inventor: TORIYAMA NORIYUKI
IPC: F16D65/09
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the ensuring of an installation space for a wheel speed sensor from being unable due to a positional deviation of an U-shaped leaf spring, and prevent the wheel speed sensor from being damaged due to erroneous assembly of the U-shaped leaf spring. SOLUTION: A pin 7 loosely fitted in a leg part 8a of a U-shaped leaf spring 8 and a web 3c is locked at its one end 7a to a back plate 1, and is turned at the other end 7b and locked after being inserted in the leg part 8c of the leaf spring 8. The leaf spring 8 has an enlarging resilient force by which a shoe 3 is resiliently held. A projecting piece 8 which is provided at the outer edge of the leg part 8a of the leaf spring 8, is inserted in a hole 9 in the shoe 3. Thus, the projecting piece 8 can prevent the leaf spring 8 from being displaced toward the center of a drum brake due to engagement with the inner edge of the hole 9, thereby making it possible to install a vehicle speed sensor 40. The leg part 8a is provided with a stopper 8f for restraining the leg part 8c from approaching the leg part 8a. Thus, even though the projecting piece 8e comes off from the hole 9 and rides on the web 3c, the approach of the left part 8c toward the leg part 8a can be harder as the left part 8c can more easily engaged and disengaged to and from the pin end part 7b thereby making it possible to prevent the sensor 40 from being damaged by the projecting piece 8e due to practical use of the U-like leaf spring which has been erroneously assembled.

The tensile spring 8 is supported to the step and bent to a periphery direction. A load is given to both rings 3, 4 by the tensile spring 8 and thereby, the state contacted to the push-press plat 1 on the one side and to the diaphragm spring 6 on the other side is kept permanently.

Title: Inspection of bonding
Inventor: ISHIDA TAKESHI
IPC: H01L21/60
Filed: 1985-04-15
Abstract: PURPOSE:To inspect whether bonding is performed properly or not during the bonding operation and improve operation efficiency by detecting the waveform of a high frequency current flowing through a capillary. CONSTITUTION:Inspection of bonding is carried out based upon a waveform of a high frequency current applied during the bonding process. The current intensity of the high frequency current outputted by an ultrasonic oscillator 15 is subjected to analog/digital conversion by an A/D converter 18 and memorized in a memory 21. The current intensity is added by an adder 22 and supplied to a judging circuit 29. The output of a divider 23, obtained by dividing the added current intensity, is supplied to a normalizing circuit 24 and a normalized pattern is formed. The difference between the normalized pattern and a pattern obtained when the proper bonding is performed and memorized in a memory 25 is detected by a differential detection circuit 26. A correlative value obtained by adding the output of the differential detection circuit 26 in an adder 27 is supplied to the judging circuit 29. The judging circuit 29 judges that the proper bonding is performed if the correlative value is not more than the predetermined value and the value added by the adder 22 is within the predetermined range.
